Measuring provisioning capacity across distributed systems

ABSTRACT

Provisioning capacity measuring may be provided. First, a provisioning monitoring job may run on a grid manager that spawns a plurality of farm monitoring jobs onto a respective plurality of farms. Next, a user count for each of the respective plurality of farms may be respectively provided. The user count may comprise a number of users on each of the respective plurality of farms. An event alert may be provided when the user count for any of the respective plurality of farms is greater than a threshold.

BACKGROUND

Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.

Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This may take the form of web-based tools or applications that users can access and use through a web browser as if the programs were installed locally on their own computers.

SUMMARY

Provisioning capacity measuring may be provided. This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Nor is this Summary intended to be used to limit the claimed subject matter's scope.

DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the invention may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention. Instead, the proper scope of the invention is defined by the appended claims.

Cloud computing systems may use web application platforms (e.g. SharePoint Online™) to support tenants and users corresponding to the tenants. As cloud computing systems continue to grow and service larger customers, the system may need to continuously track the number of tenants and users that have been provisioned in various parts of the system. This information may be used to make strategic decisions regarding when, for example, to close content farms, directory services farms (e.g. SharePoint Online™ directory services (SPODS) farms), tenant placement, and when to divert traffic to utilize resources more efficiently. Conventional systems have not been able to report data real-time, typically resulting, for example, in a large lag until operations engineers can execute a query.

Embodiments consistent with the invention may track and monitor the number of tenants and users that have been provisioned throughout various parts of a system. A new provisioning monitoring job may be scheduled in a grid manager that then spawns related jobs for each farm. Licensed and unlicensed user counts may be aggregated in both content farms and directory services farms, pushed back to the grid manager, and stored in a grid database. Thresholds may be set, for example, at 50%, 75%, 90%, and 100%. If these thresholds are reached, an event may be fired to notify operations engineers.

FIG. 1 is a block diagram of an operating environment 100. Operating environment 100 may comprise, but is not limited to, a cloud computing system using a web application platform operated on the Internet. Operating environment 100 may comprise at least one content farm 105, at least one directory services farm 110, and a grid manager 115 connected together by a network. Directory services farm 110 may comprise, but is not limited to, a SharePoint Online™ directory services (SPODS) farm. While only one content farm and one directory services farm is shown in FIG. 1, operating system 100 may include any number of content farms and directory services farms. Each farm (i.e. content farm 105 and directory services farm 110) may have a limit to the number of tenants, licensed users, and unlicensed users that it can provision. A farm may comprise a collection of computer servers maintained to accomplish server needs beyond the capability of one machine. As will be described in greater detail below with respect to FIG. 3, a computing device 300 may comprise an operating environment for content farm 105, directory services farm 110, or grid manager 115.

When operating environment 100 is created, a provisioning monitoring job may be started. The provisioning monitoring job may run on grid manager 115 and may be configurable to run for all networks or a specific network (e.g. operating environment 100.) The provisioning monitoring job may then spawn additional jobs on content farm 105 and on directory services farm 110. If other content farms and other directory services farms exist in operating environment 100, provisioning monitoring job may spawn additional jobs on these additional other content farms and other directory services farms. The additional job spawned on directory services farm 110 may calculate a count of licensed users and unlicensed users within directory services farm 110, while also determining the directory services farm (e.g. directory services farm 110) in which the calculate licensed users and unlicensed users reside. These calculated counts may then be returned to content farm 105 where they are aggregated by the additional job spawned on content farm 105 to tally a count of users per content farm. The aggregation may happen on content farm 105 because an assumption may not be made that all users within a given content farm (e.g. content farm 105) reside in the same directory services farm (e.g. directory services farm 110).

The job spawned on content farm 105 may then return the counts of licensed users and unlicensed users per content farm (e.g. content farm 105) and directory services farm (e.g. directory services farm 110) to the grid manager 115 to store in a grid manager database. This may allow reporting to a central location within operating environment 100. Capacity thresholds may be defined for the various components (e.g. content farm 105 and directory services farm 110) of operating environment 100. If a component reaches, for example, 50%, 75%, 90%, or 100% capacity, an alert may fire. This gradual step approach may provide ample warning for an operations team if they need to take action to close farms, stand up new farms, or move tenants.

FIG. 2 is a flow chart setting forth the general stages involved in a method 200 consistent with an embodiment of the invention for measuring provisioning capacity. Method 200 may be implemented using one or more of computing device 300 as described in more detail below with respect to FIG. 3. Ways to implement the stages of method 200 will be described in greater detail below.

Method 200 may begin at starting block 205 and proceed to stage 210 where grid manager 115 may run a provisioning monitoring job. For example, the provisioning monitoring job may comprise a computer program that may run on grid manager 115 and may be configurable to run for all networks or a specific network (e.g. operating environment 100.)

From stage 210, where grid manager 115 runs the provisioning monitoring job, method 200 may advance to stage 220 where the provisioning monitoring job may spawn a plurality of farm monitoring jobs onto a respective plurality of farms. The plurality of farms may comprise, for example, content farm 105 and directory services farm 110. While running on grid manager 115, the provisioning monitoring job may provide farms running in operating environment 100 with farm monitoring jobs comprising computer programs. For example, the provisioning monitoring job may provide content farm 105 with a content farm monitoring job. Moreover, the provisioning monitoring job may provide directory services farm 110 with a directory services farm monitoring job.

Once the provisioning monitoring job spawns the plurality of farm monitoring jobs in stage 220, method 200 may continue to stage 230 where the plurality of farm monitoring jobs may respectively provide a user count for each of the respective plurality of farms. The user count may comprise a number of users on each of the respective plurality of farms. For example, licensed and unlicensed user counts may be aggregated in both content farm 105 and directory services farm 110. These counts may be pushed back over the network to grid manager 115 and stored in the grid database on grid manager 115.

Consistent with embodiments of the invention, the directory services farm monitoring job may calculate the user count of licensed and unlicensed users within directory services farm 110. In addition, the directory services farm monitoring job may note a content farm (e.g. content farm 105) in which the calculated users reside. The calculate user count may then be sent to content farm 105. The content farm monitoring job running on content farm 105 may then aggregate these numbers to tally an exact count of users on content farm 105. The aggregation may be performed by the content farm monitoring job running on content farm 105 because an assumption may not be made that all users within content farm 105 reside in directory services farm 110. The content farm monitoring job running on content farm 105 may then send the counts of licensed/unlicensed users per content farm 105 and directory services farm 110 to the grid manager 115 to store in the grid manager database. This may allow reporting off to a central location within the web application platform running in operating environment 100.

After the plurality of farm monitoring jobs respectively provides the user count for each of the respective plurality of farms in stage 230, method 200 may proceed to stage 240 where grid manager 115 may provide (e.g. display) an event alert when the user count for any of the respective plurality of farms is greater than a threshold. For example, if the number of users on content farm 105 has reached a first threshold (e.g. 50% of content farm 105's capacity), then grid manager 115 may provide (e.g. display) a first event alert comprising a “yellow alert.” If the number of users on content farm 105 continues to grow and reaches a second threshold (e.g. 75% of content farm 105's capacity), then grid manager 115 may provide (e.g. display) a second event alert comprising an “orange alert.” This may continue for any capacity levels. Also, the same event alert process may apply to directory services farm 110. This gradual step approach may provide ample warning for an operations engineering team to take action to, for example, close farms, stand up new farms, or move tenants or users. Once grid manager 115 provides the event alert in stage 240, method 200 may then end at stage 250.

An embodiment consistent with the invention may comprise a system for measuring provisioning capacity. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to spawn a plurality of farm monitoring jobs onto a respective plurality of farms. In addition, the processing unit may be operative to respectively receive a user count for each of a respective plurality of farms. The user count may comprise a number of users on each of the respective plurality of farms. Furthermore, the processing unit may be operative to provide an event alert when the user count for any of the respective plurality of farms is greater than a threshold.
